Multirun method evaluates LLMs via parallel runs and output divergence

By PulseAugur Editorial · [1 sources] ·

A new method called Multirun allows for the evaluation of large language models by running multiple isolated instances of the model in parallel on the same task. This approach, developed by Denis Kubilyov, uses isolated environments including separate Git worktrees and PostgreSQL branches via Neon's API to prevent cross-contamination between runs. By comparing the outputs of these parallel agents, developers can identify areas of consensus and divergence, providing insights into model reliability and uncertainty without the need for traditional evaluation infrastructure like judge models or golden datasets. AI

IMPACT Provides a cheaper and more insightful method for evaluating LLM outputs by leveraging parallel runs and divergence analysis.

    Multirun: How Running Ten Isolated Agents in Parallel Becomes the Cheapest Eval You'll Ever Run

    <p>Denis Kubilyov ran the same task through ten isolated Claude Code agents simultaneously. Each agent got its own git worktree and its own Postgres branch. All ten agents agreed completely on the schema. Then they split 5/5 on two decisions nobody explicitly asked them to make.<…
